- url access : https://vangoghworldwide.org/
- documentation : https://github.com/vangoghworldwide/linkedart
- The most important question for me is: either I send you quickly the XML files only for the paintings (because the drawings are being migrated in our TMS) and you perform the processing to generate the jsonLD and in this case, I send you as CSV files, the AAT ids of the indexations and entities persons that are present in the files. Or we wait a few weeks for the drawings to be in TMS (and for the data to be verified), and I perform the transformation of the data into jsonLD and then I send you the .json files already formatted.
- In the website for a record of an object, there is not necessarily the inventory number of the institution that keeps the object. In the documentation, there is an example with the inventory number. Moreover, I think it would be more appropriate to provide in addition to the La Faille id and the Hulsker id, our inventory number and the TMS id (our collection management database)
- Lian : The collection management system id is not used on the Van Gogh Worldwide platform, but feel free to include it in the Linked Art data if it is useful for you.
- antoine : another question comes to me in relation: you do not generate a link to the source catalog?

}- For the iconographic indexations, can I put the labels in French with the id of the getty concept or do you only need the labels in English?
- Lian : As long as you link to the appropriate AAT concept, it does not matter which labels you use. The platform uses the AAT data, not the labels, so you can choose the label that works best for you.
- Antoine : So I just put the id of the aat

For the dimensions, we also have dimensions with the frames, is it interesting for you?
- Lian : Currently the platform includes dimensions without frames only. Maybe dimensions with the frames will be implemented at a later stage.
- ANtoine : So I'm not sending you the info.
-
For the images, we do not have IIIF yet. For information, since my arrival in October, I have launched this project that we hope to see the day by the end of 2022. This raises the question of information updates because we could send you the corpus of data with our own IIIF url for the images.
- Lian : That is no problem. When you update the links to the images, the platform will be able to get them and include the new images into the platform.
- Atoine: perfect. Do you have an update schedule? For example, every yeanr or do you send the dataset back?
-
Still for the images, as you may know we are still constrained by the RMN which manages our images and does not allow us to distribute images beyond 800px
- Lian : That is no problem. The platform will accept the highest resolution you can provide or are willing to share.
- Antoine :

]- For the provenance information, we unfortunately have little information in our database today. For example, we do not have the different types of transactions except for the purchase in public collections. For the rest, we only have a list of collections to which the painting belonged. We will be obliged to follow your documentation and indicate a succession of origin by free text (https://github.com/vangoghworldwide/linkedart#provenance-statement)
- Lian : Free text is acceptable, but the consequence is that names cannot be linked on the platform. However, the XML example given provides the information in a more or less structured way. Can we help you by providing URIs for persons and institutions mentioned in the provenance information?
- Antoine : yes, possible but difficult to automate because not very harmonized.

</historique>- For exhibitions, for the id of "carried_out_by", do we also have to retrieve the id in the ULAN at the risk of confusing the physical person entity and the legal person entity (as in the case below between Paul Cassirer and his gallery. And if, I can't align, can I afford to put nothing in the id?
- Lian : We would rather have you provide an incorrect ULAN id and correct it later than provide no ULAN id at all. We guess you can safely assume that in the case of exhibitions you are dealing with legal persons. We can also give you feedback on specific cases, if that helps you.
- Antoine : Yes, I do want examples of cases that you have already encountered.

],- Still for the exhibitions, for the dates, if I do not have the precise information with the month and the year, can I put only the year under the format yyyy? (or would you prefer that I do yyyy-01-01 and yyyy-12-31)?
- Lian : Generally timespans in Linked Art are given by providing the full date and time of the begin and the full date and time of the end, even when only the year is known. But in this context it might give the false impression that the exhibition was actually held from January 1st till December 31st.
- Antoine : ok, I put the dates of type yyyy if it's ok for you. Which do you prefer? I'm also afraid that it will bring confusion.
- For the bibliographic references, I must also provide the ids of all the entities. For some of them, as for authors and/or publishers, is it possible to use uri of french directories like the one of data.bnf.fr ?
- Lian : It would be great if you could link to such ids, even though we do not yet make much use of them at the platform.
- Antoine : Ok, so still the same way with id and value in a label as in the json below

]- if I send you the json files, what is the naming of the files? the number of La Faille catalog (example F652.jsonld)?
